The manipulationis such that the film section Figure 1 is an elevatlonal new of a holdin l,'for example a colour film, is first inserted so the form of anarrow sllde, one of t e two Wa far under the mask h that it is stoppedby the having a picture aperture, while the opposite wall points ofinflection of the side portions. The 5 mask )1. is now pressed down andcovered by a second glass plate, whereupon both plates are fitted fromabove with their contents in the U- guides of the side members of thebody a. The free part I is then placed over the free edge of the plate,and when it lies flush is made fast with the edges of the side membersof the main body by bending over the lugs e and e respectively. Theholder ,now forms a small closed casing the front surface of which hasthe recess 0 corresponding to the mask, the rear surface of which recessis merely framed by the narrow members of the main and of the detachableframe parts.

As will be seen from Figure 1, one of the two side members of the part Iis deeper than the other. It has been found that in this way theassembly of the parts, which are sometimes very small, is substantiallyfacilitated.

If plates are to be inserted into the holder instead of films, the useof two covering plates is dispensed with. In this case, covering by amask and over this the arrangement of a covering plate is sufiicient. Inmany cases, covering merely with the mask or with a protecting plate oftransparent artificial substances is enough. The closed holder protectsthe photograph from damage, and permits of accommodating it in a similarmanner to microscopic preparations in cases, and above all enables readyinsertion and manipulation when used in a projection apparatus or thelike. The frames may also be readily opened in darkness or under weakillumination and their contents changed.

For the frame body itself, various materials may be used, such as sheetmetal (preferably sheet aluminium, since this may readily be writ ten onwithout etching), or a moulded material, such as artificial resin.Instead of glass plates, plates of artificial resin provided withrecesses may also be used, which simply permit of holding the film orthe like fast in the manner of masks. Finally, the separate frame partsmay also be secured together by clamping, and instead of the holderopening at one narrow side, one of the main walls may be adapted toopen, in particular when the frame is made of artificial resin.

What I claim and desire to secure by Letters Patent of the United Statesis:-

1. A holder for transparent pictures comprising a rectangular platemember shaped to form a picture aperture and having three of its edgesturned over to form three sides of a frame with inwardly facing groovesto receive. the picture, and a member of U-section adapted to be securedto the plate member to form the fourth side of the frame, said platemember being provided with an outwardly extending lug portion adapted tobe bent over to transversely enclose a portion of said member ofU-section to maintain the frame in assembled position.

2. A holder for transparent pictures comprising a rectangular plate anda U-section closing member, the said plate having three of its edgesturned over to form three sides of a frame with inwardly facing groovesto receive the picture and being shaped to form a picture opening and toform at its fourth edge a recess to receive one side of the said closingmember which member is adapted to be retained in position by lugs formedon the plate member.

3. A holder for transparent pictures comprising a rectangular plate anda U-section closing member, the said plate having three of its edgesturned over to form three sides of a frame with inwardly facing groovesto receive a plurality of pictures, said plate having a plurality ofpicture openings and provided with a recess at its remaining edge toreceive one side of said closing member, said closing member beingadapted to be retained in position by lugs formed on the plate member.

4. A holder for transparent pictures comprising a rectangular platemember and a U-section closing member, said plate member having three ofits edges turned over to form three sides of a frame with inwardlyfacing grooves adapted to receive a plurality of aligned pictures, saidplate member having a plurality of picture openings and also providedwith a recess at its remaining edge to receive one side of said closingmember, said plate member being provided with an outwardly extending lugportion adapted to be bent over to transversely enclose a portion ofsaid closing member of U-section to maintain the frame in assembledposition.
